Self-healing materials are particularly desirable for load bearing applications since they offer the potential for increased safety and material lifetimes. A furan-functionalized polymer network was designed that can heal via covalent bonding across the crack surface with the use of a healing agent consisting of a bismaleimide in solution. The polymer network is capable of >100% healing efficiency. Healing ability of fiber-reinforced composite specimens was investigated with flexural, short beam shear, and double cantilever beam specimens. It was found that solvent amount and maleimide concentration play key roles in determining healing efficiency. Furans are particularly desirable for use in remendable materials because they are abundant in secondary plant metabolites. As a result, the reported remendable system also contains large amounts of a renewable feedstock. Ongoing work includes increasing the amount of biomaterial within our composite systems and synthesizing additional bio-based monomers with desirable functionalities.
